Fig. 6: Selected plagioclase zoning profiles.
From: Cryptic evolved melts beneath monotonous basaltic shield volcanoes in the Galápagos Archipelago
Core-to-rim zoning profiles across a a glomerocrystic plagioclase crystal from a 2015 Wolf lava sample, b a plagioclase crystal from a 2015 Wolf tephra sample, and c a plagioclase crystal from a 1968 Fernandina nodule sample. MgO is typically below detection limit in (c). Characteristic 2σ analytical uncertainties are shown or are less than the size of a data point.
